This rear deck car spoiler for the new redesigned Cadillac CTS is must. It completely changes the exterior look from some what conservative to an aggressive luxury sedan on steroids. Many CTS accessories have made there mark, but this is truly the biggest improvement at an affordable price with immediate results. It is simple to install and look like no other in the industry. If your not mechanically gifted we suggest that you purchase the VIP Service Plan and have a trained aftermarket accessory installer mount it for you.
